PHOENIX (CBS5) -

A cash reward has been doubled for information leading to the arrest of anyone responsible for the drive-by shooting death of a Phoenix woman Feb. 1.

Maricopa County Attorney Bill Montgomery said the reward has been increased to $2,000.

Sandra Johnson, 51, was shot to death and three other people were wounded while they stood outside a home near 5200 S. 14th Way.

The shots were fired from a green or mint green 2007 Ford Expedition, according to the county attorney's office.

The vehicle sped away and Phoenix police said they believe four men were inside the SUV.

Johnson was pronounced dead shortly after the shooting, while a 45-year-old woman was in critical condition at a hospital, a 58-year-old woman had non-life-threatening injuries and a 42-year-old man had minor injuries, according to police.

Police said they believe more than 20 shots were fired.

The shooting may be gang-related, according to police.
